- 100% integrity tested.
- Receives a final rinse with 18MΩ ultrapure water to assure cleanliness.
- Excellent chemical compatibility. Tolerates pH 1 to 14.
- The membrane resists wetting.
Applications
- Sterile process air
- Aseptic packaging
- Tank air vents
- Fermentation process feed air
- Compressed gases
- Tolerates aggressive fluids: solvents, strong acids, & bases
